| (54) | Method and apparatus for encoding video shape and texture information |
| (57) The present invention concerns an encoding apparatus comprising: an image analysis
module that generates shape, texture and motion information from image data representing
at least a video object; a parameter coding module that adjusts texture information
generated by the image analysis module based on original shape information from the
image analysis module and encodes the adjusted texture information and shape and motion
information; a decoding module that decodes encoded texture, shape and motion information
from the parameter coding module; and a memory that stores decoded data from the decoding
module. Further, the invention relates to a method of encoding texture information
for a video object, the method comprising: performing image analysis to create a bounding
shape for a current video object plane Sk (VOP Sk); estimating texture and shape motion parameters for the VOP Sk; predictively encoding the texture and shape motion parameters with respect to a
reference VOP S'k-1; transmitting and decoding the encoded texture and shape motion parameters; and storing
a new reference VOP in memory. |
